18 Claims. (Cl. 229-29) My invention relates to a collapsible box or similar to Fig. 1, with the transverse walls or carton and particularly to a box or carton for partitions removed; Fig. 6 is a partial perspec-. Carrying eggstive view showing the transverse walls mounted The object of my invention is to construct a upon a side wall and an auxiliary side wall, the

box from a single blank or sheet of paper, or longitudinal partition not being shown; Fig. 7 60 other suitable material, in such a manner that is a partial longitudinal vertical sectional view the blank or sheet may be quickly folded and of the box as on line 7-7 Figs. 2 and 9; Fig. 8 formed into a box or carton; a further object is an end view of the box; and Fig. 9 is a transis to provide a box with V-shaped bottom ribs verse sectional view on line 9-9, Fig. 7.

The blank rib portions of the bottom of the box which rest 12 is cut to form a lid 14 and a side wall 16, and

10 upon a supporting surface; a still further obprovided with depressions to form a fold line 17. 70 ject is to provide a box having a longitudinal The bottom-sections l8 and are formed by partition formed of two layers of material for means of fold lines 19, 21, and 23. Centrally giving additional strength and rigidity to the parpositioned sections 22 and 24, are provided, and tition and also to the entire box; a still further have a fold line 25 between them, thus forming object is to form the longitudinal partition by the longitudinally extending partition 26. A fold 75 folding adjacent sections of the blank, or sheet, line 27 is provided between the partition section upon themselves so that the layers forming the 24 and another bottom section 30, which latter partition will be joined along the top edge and is joined with a bottom section 32, and another their lower edges W be in rally connected side wall 34 having fold lines 31 and 33 formed 25 with the Sections forming the bottom of the bOX;' between the same: Thus, the bottom sections 18 so a still further object is to provide a series of and 20, the longitudinal partition sections 22 and tmIISVeTSe p t ons, which are connected. at one 24 and the bottom sections and 32 constitute end with a side wall of the box and the other a bottom and longitudinal partition-formingsecends are connected with an auxiliary. side wall, tion which is connected to the lower portion of 30 Which tte s d achably secured to the other the front and rear walls of the carton and which 35 one of the Side Walls; a further Object is to p oextend upwardly toward the central portion of vide webs which extend horizontally between the the carton to form a cushion of substantially intransverse partitions and the side walls and proverted V-shape, and the section is suspended to vide the box with a lid which is hinged to one a series of cross partitions to maintain the sec- 35 of the side walls, and said lid being provided with tion in cushion-forming position. It will be seen tongues'and recesses which permit the tongues that the bottom and longitudinal partitionto be extended under the webs for locking the lid forming section is suspended from the cross parin the closed position upon the box.

so that it may be folded to form the box shown Th sections 22 and 24 f the blank 12 which in Fig. 1; 5 is a p l Perspective view, form the substantially vertical longitudinal partition 26, are provided with downwardly extending openings or recesses forming V-shaped grooves 52. Hooks 54 having shoulders 55 are formed upon the partition 26, hereinafter more fully described.

The blank 12 is first folded along the fold lines 17, 19, 21 and 23 so that the side wall 16 and the bottom sections 18 and 20 will have the angular relation shown in the end view Fig. 8. The partition sections 22 and 24 are folded upon themselves along the line 25 with the two layers or sections 22 and 24 positioned against each other, forming a longitudinal partition 26 of double thick material with the lower edges having integral connection with the bottom sections-20 and 30. The bottom sections 30 and 32 are folded along the lines 27, 31 and 33 to correspond with the shape of the bottom sections 18 and 20. Ribs 60 and 61 are thus formed which extend longitudinally of the box and add strength and rigidity- 5 held up or suspended in such a manner as to prevent contact with such a surface, whereby a permanent cushion effect is had.

The side wall 34 is folded along the line 33 into parallel relation with the side wall 16, and the transverse partition walls 36 are folded along the line 35 into a position at right angle to the side wall 34. The walls 36 are again folded along the lines into a vertical position extending at right angles to the side walls 16 and 34 and to the iongitudinal rib or partition 26 The triangular webs 46 and 47 are now positioned horizontally and connect the walls 36 with the side wall 34 and with the auxiliary sidewall 50, which latter is folded along the line 49 into a vertical position, parallel with the side wall 16. The transverse walls 36 are provided with vertically extending slots 65 between the portions 68 and 69. Said slots 65 are occupied by the hooks 54 of the partition 26; The upstanding portions 68 and 69 on the walls 36 engage the opposite sides of the hooks 54 and form braces for holding the hooks and the partition 26 against lateral movement.

The walls 36 are each provided upon their under sides with a V-shaped recess '70, and downwardly extending angular projections 71 and 72, clearly shown in Figs. 6,6, and 9. By inserting the lower portions of the walls 36 into the V- shaped notches 52 of the longitudinal rib 26, with.

the recess '70 of the walls 36 embracing the inclined bottom sections 20 and 30, the walls 36 may be readily interlocked with the rib 26.

The shoulders of the hooks 54 extend over the walls 36 and hold the latter in the grooves 52 formed in the longitudinal partition 26, thus locking the walls 36' in a vertical position, and said shoulders 55 holding them from coming out of the grooves 52. By this construction the walls 36 are rigidly held by the shoulder 55 upon the 1ongitudinal partition 26, which in turn is integrally connected with the bottom sections, thus firmly securing the walls 36 in the box. The projections 71 and 72 of the walls 36 extend into the dihedral angles formed between the downwardly converging bottom wall sections 18 and 20 and the wall sections 30 and 32, thus holding the bottom sections in the proper angular relation to maintain the ribs and 61. It will be seen that each of the-bottom sections will contact a flat urface upon which the carton is positioned along two longitudinal lines only, represented by the ribs or score lines 60 and 61.

By means of the construction described, it will be seen that the cross partitions are inserted into the openings in the longitudinal partition, being held against lateral or longitudinal movement by the longitudinal partition adjacent the lower portion of the cross partitions and against substantial longitudinal movement by engagement with the shoulders onthe cross partitions.

The auxiliary side wall 50 is positioned in parallel relation with the side wall 16. Tongues 75 formed upon the wall 16 are folded over the auxiliary wall 50 and the points 76 of the tongues are extended under the webs 46, thus detachably interlocking the walls 36 with the side wall 16 and forming the completed box. x

The lid 14 is provided with V-shaped recesse '78 and tongues 79, of obtuse angular formation, located adjacent to said recesses 78, which tongues form fastening devices for holding the lid closed upon the -box. Said recesses 78 are located in alignment with the transverse walls 36 and permit the tongues 79 to be depressed and extended under the triangular webs 47, as shown in Fig. 2, thus forming a lock for securing the lid in the closed position.

My invention provides a box of rigid construction which may be readily formed from the blank into the completed box and again opened and restored to the flat formation. That is, the carton may be folded from the collapsed condition as shown in Fig. 4 in which the various elements of the blank, such as the bottom and longitudinal partition sections and the cross partitions, are out of assembled relation, into an erectcondition as shown in Fig. l, in which the various elements are in assembled relation. In such assembled or setup condition the bottom and longitudinal partition-forming sections are in releasably interlocked condition. As stated hereinbefore, the shoulders 55 of the hooks 54 extend over the walls or cross partitions 36 and hold the latter in the grooves 52 formed in the longitudinal partition section 26, thereby providing releasable means operable upon folding or moving the bottom and longitudinal partition-forming sections from col.- lapsed condition into an erect condition, for interlocking and suspending the bottom and longitudinal partition sections to the cross partitions. The bottom and longitudinal partition sections. with the front and rear walls, form the body of the carton, and the releasable interlocking means provide for the erection of the carton from flattened or collapsed position, and also provide a positive meansfor interlocking the body portion with the cross partition, whereby relative movement of the two is prevented when the carton is erected, as will be seen in Fig. 1, for example. The longitudinal ribs 60 and 61 add strength to the box and also form downwardly inclined walls be-- low the egg compartments located upon the opposite sides of the longitudinal partition 26, which inclined walls form an added protection to insure the eggs against breakage, as said inclined walls hold the eggs in spaced relation above a table. or other flat support upon which the ribs 60 and 61 may rest, and my novel form of locking device for the lid may be-operated quickly when it is desired to open or close the lid upon the box.

. Various changes in the form and construction of the box may be made without departing from my invention.
